Defining a Server
A server provides services to other computers on a network. A server can be an expensive Windows 2008 Server, or a simple Windows XP Home computer with a shared printer.
Operating System
Server Operating Systems are more stable and secure then Desktop operating Systems
Server Operating Systems and their Software are generally much more expensive then Desktop counterparts
Server Operating Systems are generally not as easy to administer as Desktop Operating Systems
Hardware
A Server can use ANY hardware to operate, but Server Hardware is made to be more reliable then desktop hardware.
Xeon Processors are standard processors used in servers
Redundant Power Supply allow one power Supply to Fail while the Server is Still Running
RAID -- Allows for a Hard Drive to fail without crashing the Server
ECC RAM is RAM that does a self test. It is more stable then regular RAM, but much more expensive.
Types of Servers
Software features -- multiple features can be on one box
Security and Authentication gives access to network resources
Print Servers share printers on a network
File Servers share files on a network
Web/ FTP Servers provide websites on a network
Mail Servers provide email routing for an organization
Database Servers store data for outside applications
Remote Access Servers allow Internet users to access the internal network. Usually a VPN connection.
Final Thoughts...
Buy what you need... Many people buy a $5000 server when all they need is a Dell bargain bin system.

[@rorygrignard9742]

This content is still so relevant and valuable over ten years after it was created. Straight forward and to the point. Cheers Eli 🤙

[@krantimadineni585]

The thing I liked about your videos is it's not blah, blah, blah...You teach us from basics as if we don't know anything and clear the basics very well and the true part is really we have lot of doubts on our basics...Which are cleared by your teaching. Thank you very much, Eli The Real Teacher...

[@shanebagel]

This LEGEND is helping me achieve IT skills like no other youtuber. What a god damn legend. Thank you sir

[@reallycooluleh]

8 years on and this video is still the most clear cut video on youtube to help distinguishing if I need a server and to know if I need a server or a SERVER.... it's also somewhat hilarious, thanks Eli

[@evastam6995]

Crystal clear. Thanks to these tutorials I learn SOOO much easier about computers. I like also that the information is told a few times after each other. Gives me some time to make notes in the meanwhile. And somehow I dont forget it after a while. Once I have seen the video, I just know it and remember it. Great, great teacher. Thanks a lot!!

[@rputasi]

Exactly! I'm too so thankful for all the educational material he has produced. The way he explains things is just pure gold!

[@kewalagrawal6539]

As soon as he said flash...I had to check the date on which this video was uploaded 🤣

[@BijouBakson]

I completed a qualification in ICT professional but straight afterwards I went on doing other stuff. Lately I decided to get back into it as my job requires some expertise in computing. Reading my old lectures was a little bit of a challenge, until I found your course Eli. Truly a great mentor. This is 6 years old and still very relevant. Thank you.

[@user-yf1kg3op3g]

True

[@BijouBakson]

@@user-yf1kg3op3g It's been 10 years now...

[@Vegetasan6]

I decided to make a drinking game out of this video. Every time he says "servers" you take a shot of tequila. And every time he says "SERVERS" you take 2 shots of Jack Daniels. I now have alcohol poisoning.

[@shadrackkibet6767]

I like this!

[@saadsaad6422]

at end you have to learn

[@sabrinayarde818]

looooooooooool

[@rosepearl2880]

😂😂😂😂

[@MrHyde80]

Been going through your videos for 4 days now. Thanks man, good job.

[@KAAPNW]

Even after 10 years I found this video very informative, thank you so much for putting it out there.

[@xeniakekae8523]

Anyone else watching this in 2020 ? Very helpful. I'm a business student working with a Tech company now and I'm trying to learn everything i can about Networks and data centers on KZbin lol Great explanation on Servers. Thannk you!

[@shadowshade4954]

I am watching in 2022

[@dawittadesse8038]

Its extraordinarily amazing lecture, No one can have enough words to appreciate your skill and owesomeness, helpful attitude. SO POSITIVE. CAN'T THANK YOU ENOUGH!

[@PTwolf]

You're the best. I'm watching you at 1.5x speed, reminding me of what I already know and teaching all the gaps that I don't know. Thanks Bud Eli.

[@C1wangan]

Just want to say, thanks for producing your videos exactly in this way! Someone in front of me, speaking clearly and elaborating on difficult concepts with simple diagrams and writing. Thanks again

[@casamir1]

2019, still helpful!

[@Veayrua]

Agreed

[@alihamad4635]

Absolutely

[@mattscheurman1616]

Also Agree!

[@fawwaazchummun6317]

If I may add, 2020 as well!

[@OctavianTech]

Ditto in 2020

[@javazomb]

I appreciate these lessons, Eli! I received my first job as QA, and I've realized that knowing at least a little about many things is helpful (in addition to your own job description, of course). Knowing my own duties is great, but not entirely sufficient. Having a basic mental map of everything related to a software product makes me tremendously more helpful at work.

[@dan-simi6]

2018 and is still relevant, great job Eli.

[@vincentguerra8029]

Seriously!! This guy is phenomenal

[@Echoing-Faith]

2019 and still relevant

[@shamamta]

I feel like all of this is basic no matter where technology goes.

[@CAcationu2]

Thanks so much for such a simple and thorough introduction to servers. You've explained it very clearly and I don't even have lingering questions. Looking forward to seeing the rest of your classes.

[@matblackgraviton]

Eli- I sooooooooo much appreciate your dedication to putting these classes/videos together for us dummies... You're doing a great job, and I hope you keep it up.

[@acidmardigras6235]

Eli this is one of your early videos. I just want to say thanks for all the info you have provided for so many. Many landed jobs due to your awesome method of teaching. Others attempt to personalize teaching and fail miserably. Thanks, for everything.

[@TheFlyguy31]

I like the way you repeat the essential and important information to get your point across. I always enjoy your videos :)

[@toosinbeymen6304]

ECC ram. 20:35 Error-correcting code memory (Error Checking & Correction, ECC memory) is a type of computer data storage that can detect and correct the most common kinds of internal data corruption. ECC memory is used in most computers where data corruption cannot be tolerated under any circumstances, such as for scientific or financial computing.

[@chevalier5691]

You know the teacher is awesome when you can clearly understand the topics they explained while you're eating lunch

[@mrgardena26]

Eli, I would like to thank you for creating this awesome Introduction to Servers class. It has really helped me a lot with my IT career.

[@ifoxrider]

clear as crystal, i wish he is my professor in class

[@ilovesurface8]

me too

[@zach8945]

There's the server.... and the SERVER >:[

[@boxer12350]

Zachary Huberty ha. This guy.

[@jeffreyspino7525]

This is one of the first videos I have watch of yours Sir. Thank you for an outstanding job! I look forward to watching many more.

[@kaylapaul4520]

By far the best tech channel I've found on the University of KZbin. This is still very helpful almost a decade later.

[@SheMeetsCity]

I am only halfway through the video, but I must say this is EXTREMELY helpful! New subbie here!!

[@annoyingjareviews9797]

this video uploaded 2011.....the sky004 exam released 2015....dont think this video would be helpful to me.

[@alexnezhynsky9707]

Subbie... That's the first time I hear that. Lol

[@shamamta]

Your comment is 3 years old. I'd like to know how much these videos impacted you professionally.

[@laxmisidhu4483]

u r the best man on the internet with very wide and deep understanding on subject and know how to explain . thankyou so much Eli

[@jonathandixon7518]

+The Gamer Kid wow.........

[@josephskorich7029]

Carey Holzman is a good one 2

[@waal2waal842]

Eli is among the most clear and compelling of the trainers on the net - this servers discourse was excellent

[@jonathanzuniga3681]

Thanks for the great clips! I've watched many of the ones you've uploaded, and eventhough I've been in IT and worked as a netadmin and sysadmin for a while now, I still learn some new stuff from these clips! Great teaching skills!

[@marcushouse3989]

This guy is really good. He is articulate and clear. I understand everything he is saying with no background in this field. Well done. I intend to watch more of your classes.

[@Deanmartinification]

Marcus House me

[@MrFooSteven]

Exactly. Most of the time, if you don't like a teacher/lecturer's tone of speech/cadence you can lose interest easily. No matter how interesting or easy the subject is.

[@elithecomputerguy]

@evolagenda I'll be doing more of the practical theory classes shortly. I just reopened my computer shop last month so I've been busy getting that running smoothly, and haven't had time to do new classes.

[@avrumyisrael]

Hey, can you do a video on how to log in a client to a server?

[@miroslavpenchev6292]

Legend! This is the very first video from your channel which helped me become a system administrator and I still recommend it to people starting with servers. Respect!

[@David_F579]

The best explanation of severs I have seen. Have watched about 70 of Eli's video tutorials now and he is superb.

[@Lurch1111]

Very helpful video; I'm about to start an MCSA course in Windows Server 2012 & I have no server/networking background at all. Looking forward to checking out your other videos!

[@alan99yu]

THANK YOU SO MUCH FOR ALL YOUR TRAINING VIDEOS.

[@TxRiverElf]

First and foremost, THANK YOU!!! You are the rare breed of educators, those with a natural aptitude for teaching and a notable joy for sharing information, honestly!!! I am on the verge of purchasing a now outdated but still handy, Dell 1950 series server with dual processors. And I am (was, thanks to you) completely 'server' ignorant... hence surfing youtube for info. My original notion was to simply use the big hds for data backup... (I am an avid genealogist) but NOW I see there could be many other potentials to consider.. I DEFINITELY SUBSCRIBED and am eager to follow your channel to learn more! Thank you, for being you!

[@schhh26]

I love this! I'm meant to be doing a project during my IT internship, and while my colleagues are all amazingly helpful and patient (and point me to the right resources), this is a great overview to someone new to the field - and a necessary foundation to understand more specialized material. Great job!

[@AsifAnsari01]

its looking like a prisnor is talking about server in a jail

[@messiblaugrana]

I almost died laughing seeing your comment! You're 100% right! Also to mention that when I look to his face,he has blue hands :D

[@thomasxeon1912]

Even prison are resourceful than viewer in KZbin....

[@AsifAnsari01]

Ha ha ha... Zo, i might plan it in nxt vacation

[@SamsungasNFS196]

Thank You for these lessons ! It's nice to have such a honest teacher :)

[@LeighOlah]

I love These videos. They are clear and precise, but easy to follow. You use the board or items to show and make the discussion clear. GREAT JOB! Keep going.

[@subramaniyamrajendaran1559]

I don't often stop to write comments. But you are one amazing tutor...it was so clear and I watched the entire 53 min video in a stretch and just felt like 5 mins passed. Thank you

[@robertankeny3573]

Really helpful videos - you're a great teacher.

[@jasonjones8969]

This is very helpful and you explain the topic in an easy to understand way. New sub :)

[@Dodizthongs4221]

I cant believe this guys videos are on here for free.. I paid a lot of money for my education and the classes weren't as nearly as informative and concise as this guy is!!! LOVE IT.

[@deeahmed5721]

Thank you so much for the clarification I have taken so many courses at the university over the years and servers were the most talked about yet most difficult topic to understand and non of the professors explained it well enough they just expected us to know without clarifying the functionality but I love how you broke it down !

[@tysonvanburen6800]

Eli the computer guy! I'm currently attending school for Computer Science and I feel like all of my professors need to take some teaching lessons from you. Thanks for all of your videos man!

[@elithecomputerguy]

They are not really used very much anymore. Once NAT became a standard feature in all routers/ Modems the need for Proxy's almost vanished. There are a few uses for them, but not for the general public or the average admin. I'll do a class on building a SQUID proxy at some point though... ( I also did a class on sing Web Proxy Servers for Hacking, under the Hacking playlist)

[@cris1977]

Excellent video ! i've learned so much ! your way of teaching is fun, clear to understand, and I really value the fact that you recap the class's key points to understand/remember along the way, as well as at the end of the video in a clean, short, and objective way.

[@IamusTheFox]

Guys, I just got fired because I tried installing Windows XP as a server operating system yesterday. I kid, I do genuinely appericate how timeless this video actually is. Fantastic video, great job.

[@ramirez368]

Just my thoughts....for the guys that comment and said that you "Eli the Computer Guy" repeat yourself too much I would say they are in a higher level of understanding, and they need to be taking classes at MIT, you are wasting your time watching this and this goes for Elvin Novruzov and Daniel Cederberg!!!!.....go run, and get a scholarship this is too minor for you......now days everything is about shortcuts!!!

[@oscarthecomputerguy]

53:41 Minutes of my life I never get back. But who cares? This is the shit! Thanks for your Information Eli, I'd really appriciate that!

[@tomasapostol1901]

Great, as always, Mr. Etherton. Twelve years after, and still useful and relevant material. Thank you for all your classes. I've learnt so much following them. (GBY)

[@reubenfang421]

Thanks Eli! I cannot believe how easy you made it understandable (without any visuals!). Great stuff and can't thank you enough!

[@zcarenow]

Are there any videos about troubleshooting servers or the most common issues that a server admin faces day to day ? technical support issues.

[@quincypalmore3619]

I think the term for "SERVERS" is "Dedicated Server"

[@shubhammittal9764]

You can use it if you want, but I think by the dedicated server it is usually meant that the whole server is given as a service to one customer in comparison to a shared server. It's probably a term used in commercial world.

[@paradisjr45]

Quincy Palmore Hey Tuff Guy, this video is closer to 10 years older than you are correct =) Juss say'n , Maybe you've not been listening. I wanted to call you a fukn' Class A Idiot ... but you're probably not even "Dedicated" =)

[@angeloasis5125]

By far the BEST channel for IT related topics I've encountered on KZbin! Thanks heaps man!

[@David_F579]

This is a really excellent video - explained what servers were very clearly. Thank you. The key section for me was the bit where u clarified that all these server functions could actually be on the one physical computer.

[@dimitri004]

there are servers and then there are SERVERS!!!

[@daniellee6912]

mac servers are a thing?

[@elithecomputerguy]

+Daniel Lee yup... www.apple.com/osx/server/

[@daniellee6912]

Eli the Computer Guy​ I had no idea apple produced servers... thanks!

[@nelsonariza4075]

+Daniel Lee Apple's grandaddy can be argued to be Unix. But basically you can do some cool things, I remember setting up a small mail server back in the day with a G3.

[@armandolagente]

+Daniel Lee A lot of schools use them. I can think of several schools here in northern montana, and they all have mac labs, with mac servers. By schools i mean k-12, I'm not sure about the collegiate level.

[@ejisyopicus8988]

I think a better argument would be that apple is Unix's neuronetics abominations.  They are related, but in the way that a human is related to a DNA-altered-poisonous-gargantuan-fish/mammal-humanity-destroying-monster.

[@memoimy467]

November 2019, and yet still relevant. Excellent content, thank you.

[@dinliebe]

Thank u Eli. Great work! In computing we learn to communicate clearly to non-technical people, I don't get why most of them don't make use of these skills in many tutorials where needed. You make it understandable. Thanks

[@bebmerli3392]

How do you get the IP of a server

[@andrewjuarez9217]

Open command prompt and run ipconfig

[@tmtrainerred9968]

or open terminal and type "ifconfig"

[@elvinnovruzov5775]

this video could be 15 min long

[@Rosstino1]

Elvin Novruzov and so do all his other videos.

[@cuppensmaarten]

Rosstino1 I like that he takes his time for the people that need it

[@tapiwakay]

Repetition is the key to learning effectively. He's catering to novices here, you might need to find or create your own advanced user tutorials, we'll subscribe to you!

[@elvinnovruzov5775]

tapiwakay i'm also novice but i use replay button if i need repetition

[@connorbaker4159]

Elvin Novruzov He likes to ramble.. plus it is better to keep the info in your dumb brain

[@ravir5715]

I am in Financials application field for the last several years but never acquired basic understanding of the underlying IT infrastructure. Your tutorials really helped me. THANKS.

[@HowardLen]

This was an amazing introduction, you are an amazing teacher. It is hard to believe how much more I know about servers in one hour. Thank you so much.

[@eragg0]

this is only video which made to see illusion: never ever wear orange shirt. Hands look blue time to time if just looking his face

[@IsmailYusof797]

Yep, I noticed that too! Thought there was something wrong with the screen monitor but when I start looking at the hands there it was ok.

[@longlivethe80s]

LOL....I'm glad I'm not the only one that noticed.

[@Arthurbn]

Shit, thought I was going crazy. Good to know others noticed it as well.

[@anierutan1989]

Ya me too

[@wilmermendez4187]

2019..anyone?

[@TheZakev]

yes

[@sabrinayarde818]

yuppppppp

[@peterlondon9453]

2022

[@swatigopalan913]

I admire your clear presentation. Without any script you gave the tutorial about server from your own words. Its excellent. I consider this course as Server 101...Thank you for sharing and your time.

[@lekhshodhan1805]

This is the best piece of tutorial for simple and summarized understanding of servers even today.

[@TheChannel9009]

male servers :)

[@Deanmartinification]

TheChannel9009 me

[@JewLiSmile]

You really do need some pictures when you explain something because people will not watch this 53 minutes video of yours. Get your audience some showmanship.

[@paradisjr45]

Beantard Right ? Wait a second .... the Judges just relayed to me that the FACT your User Name is Beantard, excludes you from giving ANY ADVICE EVER =( & Get a tan for crying out LOUD !

[@Velli1987]

Thank you so much for this tutorial. I swear breaking technology down to an understandable point is quite the art form to master and very few "professionals" are able to attain it. Thank you for being a great artist.

[@johncortes3831]

Thank you very much Eli, this was very helpful, since I was taking a Microsoft designed course in order to get me into this whole topic. I was getting a little bit overwhelmed since I am new to this, but fortunately I found your video and seeing that acquainting knowledge in a more appealing way is possible has definitely motivated me again. By the way, I am impressed by the amount of content you have in your channel, I am definitely going to seize it, you have just gotten a new subscriber from Colombia. Keep up the good work Eli.

[@dimosanagnostopoulos]

man i like your videos but you have to stop repeating yourself! what i mean is that you say everything two or more times! you do not say your points only once but twice or more!

[@greendunn1]

Thats for noobs like me!!! I dont quite get in on first go around, but the second or third, it sinks in.

[@AlexanderDubouvier]

I see what you did there...

[@paradisjr45]

Dimos Anagnostopoulos Man, nuthin' get's by you Huh ? What I should've said was ... your last name sounds like someone tryin' to shit an Extinct Dinosaur =) You Greeks can't know everything ... it's not in your DNA =(

[@danielcederberg9894]

Why did you repeat everything 3 times??? It's a video, if people didn't understand you the first time, they can rewind...

[@danielcederberg9894]

otherwise it was good.

[@paultalbot722]

Daniel Cederberg on the other hand its a video you can fast forward.

[@stylz1]

Daniel Cederberg One thing I've learned when it comes to learning technical things is that the best way to learn and retain information is through slightly different iterations of the same thing. That's why in school for instance you have a book you are expected to read as well as lecture over the same info. I for instance took an A+ software, A+ Hardware, and Network+ class, reading the required material while also reading a book not required for either class, all in one semester. The overlap and slightly different iterations definitely helped solidify the information in my head. I passed all three exams by 110 points or more all within a week. Not saying this couldn't be trimmed down, but to stick to a "one pass of info" routine has its drawbacks.

[@schhh26]

Because it's a lecture. People aren't familiar with the information already (if they were, they'd watch a five min refresher or skim over an article), so repeating info makes it stick better. They might also miss something important the first time, so doing it like this ensures the viewer can just pop one of Eli's videos on and sit back without worrying about retaining briefly mentioned facts like they would have to with a very efficient and concise video - retention kind of happens automatically.

[@Yathoom2]

I stumbled upon this video through video search, and I'm glad I clicked on the first thing or the second !! I found. Very elaboration and very clear. I like how he speaks like a teacher and how down to the basic and up to explain things. I had a friend who tried to explain this to me, but it just only made sense when I saw the video. Thank you Eli. (2 thumps UP)

[@SRHarkreader]

Well done!!! The content is comprehensive, related, and clearly and consistently delivered. Also, the summary at the end is a great review, Again, nice job!

[@vivekbisht6051]

This is by far the most well structured video on introduction to servers.

[@durbabanik3372]

It straight away go inside my brain and I can picture it right in front of me the way you teach.Excellent Job.Thanks a Lot!!

[@jakeupmickey8175]

All I have to say is you are great, great because you leave nothing out with clarity and refresh with dependency which key why go to school when we have you. I can not thank you enough.

[@mypagedotcom5804]

This is just what every beginner needs to move on with a lot of complexities in creating a server. The terms are really easy to understand. Unlike other video posters, this one is accurate and straight to the point. This video can even help the professionals already in refreshing what they sometimes forget.

[@FabrizioCARENA]

Great introductory video! Thanks for keeping always the HUMAN (and down to earth) aspect alive while delivering! Thank you!

[@sweetboyforlife]

like always , love your video . love the fact that you went in " full details " explaining every thing about servers and how they work !

[@FroBoy696]

Eli I just want to thank you for these videos. They're great for beginners and a WONDERFUL refresher course for IT specialists. Especially for Network Administrators like me!

[@mairca80pais96]

Great job Eli. Recently found your videos and really enjoy learning about IT. You make the concepts so much easier to understand.

[@starmoonxy]

thank you eli!!! you have a real knack to explain hard stuff in simple layman terms! you're unlike many boring IT guys out there. simply amazing

[@MrFOOTBALLINSIDE]

Thanks a lot Eli, really appreciate you taking time to explain everything, you made it easy for me to understand about servers and many other related things!!! Thanks Again!! Keep up the great work!

[@hocongluan788]

This vid stand for the bright side of KZbin nowadays. Comment from 2020. Still worth it

[@curtpriestley2107]

You are awesome, man. Learned more relevant material for my job from you than I did in the past 3 years being back in school and finishing up my degree. Plus you're an IT guy on youtube that actually has a personality, and that I want to listen to, haha

[@munmoonghosh4093]

Wow! one of the best online teachers i came across. Already done watching 4 videos of 1 hour each. Thank You! :)

[@vivauruguay]

Thanks Eli you have made my life a lot easier since coming across you. The things a have learned from you in 1 hour i did not learn from a network course i did over 4 years , once again thanks and keep the good work you are doing for humanity.

[@Arielofjudahservingyah]

Your tutorials are excellent, you are an amazing and hilarious presenter and teacher. I have fun sharing your information with students eager to learn and i enjoy them myself acts as great refreshers.kudos to you Sir Eli.

[@yulduzetta]

Eli! Every video you make here, makes my life 100 times easier in understanding IT stuff. TNX a lot!

[@rasheedah1122]

Eli, im now so addicted to your channel. Been here since morning :-) Great teacher

[@akosiboyet30]

I feel like listening to a very patience instructor.. trying to teach very difficult information to a newbie like.. Sir very much appreciate your video..

[@Gwen3344]

Wow, a geek who can teach! This video was so well done; the information is presented with clarity and totally provided what I've needed for so long to demystify the world of servers. You certainly recognized what was missing -- a general discussion about server concepts and functionality that is not tied to a vendor product or professional certification. Finally, a discussion for the rest of us! Bravo!! I thank you so much. I am now eager to complete this track and view your other videos.

[@Shai87Levi]

I think you're the best lecturer I ever faced. Thank you and keep up your GREAT work!
